7 Preface Computer Science is a young discipline. Many of today s Computer Science teachers have their disciplinary roots still elsewhere. Consequently, curricula differ dramatically, certainly between countries, and there is little if any agreement on what the fundaments of this discipline ought to be. Even if international organisations such as IFIP, IEEE, and ACM are putting considerable effort in developing curriculum guidelines, these do not rise above the tentative, and their application as well as their validity in different parts of the world is a matter of trial and error. An additional problem is the lack of international standards for establishing a specific educational level: university or academic turn out to allow for widely different interpretations and, consequently, levels of expected achievement. So far, international Computer Science conferences on education or with education tracks have mainly featured examples of curricula and experience reports. Valuable though these are, the time is ripe for reports on systematic research on computer science learning and education. What are the fundaments of the domain? How best to structure it? How to incorporate traditional as well as novel techniques for teaching and learning? How to design suitable learning environments? These are not only novel questions for this just emerging discipline, they also very much need to be addressed as education in this young discipline certainly is not a trivial matter, the more so since it itself is still evolving at an unprecedented speed. Our conference is an early effort to stimulate and coordinate this type of educational research by creating a stage for its dissemination. We aim at an international audience, and intend to create a truly global community of research. We will all benefit from each others early attempts, from the different types of issues that seem relevant, from the different research backgrounds that contribute their flavours to the concepts and frameworks that infuse and enrich our research. We hope to discover both common ground and an inspiring variety of approaches. Research on Computer Science Education stands to profit from that. Managing quality at the start of a new research community implies bootstrapping. We were happy to cooperate with ACM s Special Interest Group on Computer Science Education (SIGCSE) in identifying reliable and expert reviewers, and to spread the call for submissions. This volume contains the first harvest from an exciting new field. We hope it serves its goals: helping to set the tone and to define the research domain, as well as stimulating the development of an international research community. We thank our hosts, NIOC, the Open University of The Netherlands, and the Zuyd University for their support and for providing the logistics to our meeting. We hope these proceedings increase awareness among the international world of Computer Science education researchers and stimulate discussion and collaboration.
